SMTP error from remote mail server after RCPT TO:<your address>:

Thanks for the fix, it solved half of the problem. I can now export from SIB to SIL and properly use the editor to update my translations, but when I export from SIL to SIB again it won´t work, the SIB file will be become corrupted

I have sent you another e-mail with more details and a file for testing, please check this. The problem was that we could not translate, now we have updated the translations but we cannot input back to the sofware because we use .SIB format inside the software, dynamically loading translations from a DLL

Thank you for sending files. Actually, it looks like your initial SIB file is not quite correct. There are several forms that stored as UTF-8 and others stored as usual. As result when SIL Editor converts SIB to SIL the resulting SIL file contains mixed data. Some items are in UTF-8 but others are not. Could you please check your initial SIB file and ensure that either all forms are in UTF-8 or in usual format?
